is there a sneak peek of chapter 2 in SoN?

before the Остаться в живых hero (book 1) came out Ты could have a sneak peek of the first 2 chapters, so how come i can only find chapter 1 in the son of neptune? is there 2 sneak peek chapters или is there only one? and if there is only 1 chapter will R.R. give us a sneak peek of chapter 2 before the book comes out?
